CONTROLLING MECHANISM FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application led August 13, 1910. Serial N o. 577,053.

To all 'whom t may concern:

Be it known that I, RUSSELL HU'FF, a citizen of the United States, andresident of Detroit, Vayne county, State of Michigan, have inventedcertain new and useful lmprovements in Controlling Mechanism forMotor-Vehicles, of which the following is a specification.

This invention relates to controlling mechanism and more particularly tosuch mechanism as is emplpyed for controlling the gears, the brake, orother controlled mechanism of a motor vehicle.

The object of this invention is to simplify the construction of suchmechanism and to arrange the parts in a most compact and eiicient form.

The invention will be described in connection with the accompanyingdrawings, in which:

Figure 1 is a side elevation of a portion of a motor vehicle with acontrolling mechanism embodying my invention; Fig. 2 is a' verticalsection through the parts shown in Fig. 1 and showing some of the partsin elevation; Fig. 3 is a plan view of the lever guiding members showingthe levers in section; Figs. 4 and 5 are side and end views,respectively, of the lever bracket; and Figs. 6 and 7 are detail viewsof parts.

Referring to the drawings, 10 represents one of the side members of amotor vehicle frame, to which a bracket 11 of peculiar form is securedas by rivets 12. This bracket 11'is provided with a main transversebearing 13 in which are mounted a pair of concentric or nested shafts 14and 15 connected respectively with the brake lever 16 and the gearshifting or controlling lever 17. The bracket 11 is further providedwith a pair of separated upwardly extending 4arms 18 to which the guidemembers 19, 20 and 21 are secured by bolts 22 as shown particularly inFig. 3. These guide members form the guides for the controlling andbrake levers.

A voke 23 is secured to the outer end of the shaft 14 as by brazing andpins 24.

nected to the inner shaft 15 and mounted inside of the brake leverwhereby the brake lever shaft which must bear the greater strains may bethe outer and stronger of the two nested shafts. The brake lever 16 isprovided with a la'tch 26 which cooperates with the teeth 27 on theguiding member 19 for setting the brake in various positions.

The gear shifting lever 17 is adapted to move forwardly and backwardlyin a slot 2S formed between the guide members 20 and 21 to obtainvarious forward speeds of the vehicle and is also adapted t0 be movedlaterally or transversely into the notch or recess 29 formed in theguide member 21 to mesh the reverse gears of the vehicle. A suitablelatch 30 operated by a thumb piece 31 and a rod 32 may be provided toprevent the gear shifting lever being moved into reverse positioninadvertently.

In the end of the operating shaft 15, which may be connected with theforward speed gears of the vehicle, is a plug 33 brazed or secured tothe shaft 15 by pins 34, and this plug projects slightly from the shaftand is formed with a pair of jaws 35 adapted to clamp between them atrunnion piece 3G, the clamping action being obtained by a bolt 37. Thusthe trunnion piece 36 is securely held against either rotary or endwisemovement and no Cotter pins or other securing devices are necessary.

The gear shifting lever 17 is divided adjacent its connection with theplug 33 and is formed with trunnion bearings 38 which fit the trunnionpiece 36 and it will be seen thatthis connection causes the operatingrshaft 15 to be rocked bv the forward and backward movements of the lever17 and permits an independent movement of the lever 17 into the notch29. this latter movement being accomplished by rocking the lever on thetrunnion piece 36.

The bracket 11 is further provided with an integral forwardly extendinglug 39 upon which are two separated ears 40 formingr a bearing for theDivot bolt 41 and the operating lever 42. This operating lever has anarm 43 which is connected by a link 44 with the downwardly extending end45 of the gear shifting lever 17. The lever 42 is also provided with anarm 42' which is connected with the reverse gear shifting mechanism.Said end 45 is formed with a. segmental piece 46 which moves in a grooveor slideway 47 in the link 44 whereby the backward and forward movementsof the lever 17 are not conveyed to the operating lever 42, but thetransverse movement of the lever 17 causes the lever 42 to rock upon itspivot and through other suitable connections, not shown, to operate thereverse gears of the vehicle.

It will thus be seen that all the bearings for the levers together withthe guides are supported on a single bracket and that all these bearingsare integral therewith whereby the bearings and the other parts may beaccurately machined and the parts may be easily assembled with a minimumof eX- pense. The lug 30 and the ears 40 thereon project forwardly so asto lie in substantially the same plane with the body of the bracket sothat the bearing lugs will not project beyond the bracket any more thannecessary, thereby not only improving appearances but also rendering thestructure more compact since the operating lever 42 can be located belowthe side member with the greater part of it within the outside limits ofthe side member. It will be seen that the operating lever is curved soas to permit this construction.

By connecting the controlling lever to the inner shaft and the brakelever to the outer shaft the controlling lever can be located inside ofthe brake lever nearest the chauffeur so that vthe operation thereofwill be facilitated. This is of special advantage in view of the factthat the controlling lever is moved inwardly and therefore away from thebrake lever for reversing. This construction also permits the outershaft to become the brake shaft and thereby can be made much strongerfor the same amount of material. This arrangement of the levers andshafts results in a very compact and simple arrangement.

It is obvious that various changes may be made in the details ofconstruction without departing from this invention, and it is thereforeto be understood that this invention is not to be limited to thespecific construction shown and described.

Having thus described my invention,what

I claim is:
